ABSTRACT

A control device for a conditioned space includes a first face and a second face. The first face is configured to be mounted on a surface at a height accessible by a user. The second face has a display. A first axis normal to the display is angularly offset by an angular amount from a second axis normal to the surface. The first axis normal to the display is substantially parallel with a line of sight associated with the user at an access distance from the control device.

BACKGROUND

The present disclosure relates generally to control systems that control environmental conditions of a building. More particularly, the present disclosure relates to a touchless building control device of a building system.

Systems of a building may include various controllers configured to generate control decisions for heating or cooling equipment or systems. The controllers can, in some cases, be thermostats. Thermostats can be utilized in both residential and commercial building systems. Thermostats can receive, or themselves measure, environmental conditions such as temperature and generate control decisions based on setpoints and/or the measured temperature for operating the heating or cooling equipment or systems.

Building control devices include physical displays for presenting measured or control information to a user and for receiving input from the user, e.g., a user desired setpoint or operating schedule. Building control devices typically include physical buttons or touch sensitive surfaces for interacting with the building control device. However, in some cases, the physical buttons and touch sensitive surfaces are prone to signs of use (e.g., wear, smudges, finger prints, etc.) and may be difficult to keep clean, ultimately contributing to the spread of disease and an unsightly control device. Traditional displays on building control devices are parallel to the mounting surface, and consume large amounts of power. In some cases, the building control device is mounted high on a wall that is not easily accessible by all users. Furthermore, typical building control devices often require the use of a physical lock box to selectively provide access to the thermostat, with varying levels of success.

DETAILED DESCRIPTION

Overview

Referring generally to the FIGURES, systems and methods are shown for a touchless building control device, according to various embodiments. A touchless building control device may be a thermostat or other control device that does not require a user to touch the device. For example, the touchless building control device may include sensors to detect touchless motion, and connections to equipment or connections to a remote device or connections to a network but includes no touch controls on the interface for allowing a user to interact with the touchless building control device.

HVAC System

Referring now to FIGS. 1-3 , an exemplary HVAC system in which the systems and methods of the present disclosure can be implemented are shown, according to an exemplary embodiment. While the systems and methods of the present disclosure are described primarily in the context of a building HVAC system, it should be understood that the control strategies described herein may be generally applicable to any type of control system that optimizes or regulates a variable of interest. For example, the systems and methods herein may be used to optimize an amount of energy produced by various types of energy producing systems or devices (e.g., power plants, steam or wind turbines, solar panels, combustion systems, etc.) and/or to optimize an amount of energy consumed by various types of energy consuming systems or devices (e.g., electronic circuitry, mechanical equipment, aerospace and land-based vehicles, building equipment, HVAC devices, refrigeration systems, etc.).

In various implementations, such control strategies may be used in any type of controller that functions to achieve a setpoint for a variable of interest (e.g., by minimizing a difference between a measured or calculated input and a setpoint) and/or optimize a variable of interest (e.g., maximize or minimize an output variable). It is contemplated that these control strategies can be readily implemented in various types of controllers (e.g., motor controllers, power controllers, fluid controllers, HVAC controllers, lighting controllers, chemical controllers, process controllers, etc.) and various types of control systems (e.g., closed-loop control systems, open-loop control systems, feedback control systems, feed-forward control systems, etc.) as may be suitable for various applications. All such implementations should be considered within the scope of the present disclosure.

Referring particularly to FIG. 1 , a perspective view of a building 10 is shown. Building 10 may generally include a building management system (e.g., a system of devices configured to control, monitor, and manage equipment in or around building 10). The building management system can include, for example, a HVAC system, a security system, a lighting system, a fire alerting system, any other system that is capable of managing building functions or devices, or any combination thereof.

Building 10 is served by an HVAC system 100. HVAC system 100 can include a plurality of HVAC devices (e.g., heaters, chillers, air handling units, pumps, fans, thermal energy storage, etc.) configured to provide heating, cooling, ventilation, or other services for building 10. For example, HVAC system 100 is shown to include a waterside system 120 and an airside system 130. Waterside system 120 can provide a heated or chilled fluid to an air handling unit of airside system 130. Airside system 130 can use the heated or chilled fluid to heat or cool an airflow provided to building 10.

HVAC system 100 is shown to include a chiller 102, a boiler 104, and a rooftop air handling unit (AHU) 106. Waterside system 120 can use boiler 104 and chiller 102 to heat or cool a working fluid (e.g., water, glycol, etc.) and can circulate the working fluid to AHU 106. In various embodiments, the HVAC devices of waterside system 120 can be located in or around building 10 (as shown in FIG. 1 ) or at an offsite location such as a central plant (e.g., a chiller plant, a steam plant, a heat plant, etc.). The working fluid can be heated in boiler 104 or cooled in chiller 102, depending on whether heating or cooling is required in building 10. Boiler 104 can add heat to the circulated fluid, for example, by burning a combustible material (e.g., natural gas) or using an electric heating element. Chiller 102 can place the circulated fluid in a heat exchange relationship with another fluid (e.g., a refrigerant) in a heat exchanger (e.g., an evaporator) to absorb heat from the circulated fluid. The working fluid from chiller 102 and/or boiler 104 can be transported to AHU 106 via piping 108.

AHU 106 can place the working fluid in a heat exchange relationship with an airflow passing through AHU 106 (e.g., via one or more stages of cooling coils and/or heating coils). The airflow can be, for example, outside air, return air from within building 10, or a combination of both. AHU 106 can transfer heat between the airflow and the working fluid to provide heating or cooling for the airflow. For example, AHU 106 can include one or more fans or blowers configured to pass the airflow over or through a heat exchanger containing the working fluid. The working fluid can then return to chiller 102 or boiler 104 via piping 110.

Airside system 130 can deliver the airflow supplied by AHU 106 (i.e., the supply airflow) to building 10 via air supply ducts 112 and can provide return air from building 10 to AHU 106 via air return ducts 114. In some embodiments, airside system 130 includes multiple variable air volume (VAV) units 116. For example, airside system 130 is shown to include a separate VAV unit 116 on each floor or zone of building 10. VAV units 116 can include dampers or other flow control elements that can be operated to control an amount of the supply airflow provided to individual zones of building 10. In other embodiments, airside system 130 delivers the supply airflow into one or more zones of building 10 (e.g., via supply ducts 112) without using intermediate VAV units 116 or other flow control elements. AHU 106 can include various sensors (e.g., temperature sensors, pressure sensors, etc.) configured to measure attributes of the supply airflow. AHU 106 can receive input from sensors located within AHU 106 and/or within the building zone and can adjust the flow rate, temperature, or other attributes of the supply airflow through AHU 106 to achieve set-point conditions for the building zone.

Referring now to FIG. 2 , a block diagram of waterside system 120 is shown, according to an exemplary embodiment. Waterside system 120 can include a subset of the HVAC devices in HVAC system 100 (e.g., boiler 104, chiller 102, pumps, valves, etc.) and can operate to supply a heated or chilled fluid to AHU 106. The HVAC devices of waterside system 120 can be located within building 10 (e.g., as components of waterside system 120) or at an offsite location such as a central plant.

In FIG. 2 , waterside system 120 is shown as a central plant having a plurality of subplants 202-212. Subplants 202-212 are shown to include a heater subplant 202, a heat recovery chiller subplant 204, a chiller subplant 206, a cooling tower subplant 208, a hot thermal energy storage (TES) subplant 210, and a cold thermal energy storage (TES) subplant 212. Subplants 202-212 consume resources (e.g., water, natural gas, electricity, etc.) from utilities to serve the thermal energy loads (e.g., hot water, cold water, heating, cooling, etc.) of a building or campus. For example, heater subplant 202 can be configured to heat water in a hot water loop 214 that circulates the hot water between heater subplant 202 and building 10. Chiller subplant 206 can be configured to chill water in a cold water loop 216 that circulates the cold water between chiller subplant 206 and the building 10. Heat recovery chiller subplant 204 can be configured to transfer heat from cold water loop 216 to hot water loop 214 to provide additional heating for the hot water and additional cooling for the cold water. Condenser water loop 218 can absorb heat from the cold water in chiller subplant 206 and reject the absorbed heat in cooling tower subplant 208 or transfer the absorbed heat to hot water loop 214. Hot TES subplant 210 and cold TES subplant 212 can store hot and cold thermal energy, respectively, for subsequent use.

Hot water loop 214 and cold water loop 216 can deliver the heated and/or chilled water to air handlers located on the rooftop of building 10 (e.g., AHU 106) or to individual floors or zones of building 10 (e.g., VAV units 116). The air handlers push air past heat exchangers (e.g., heating coils or cooling coils) through which the water flows to provide heating or cooling for the air. The heated or cooled air can be delivered to individual zones of building 10 to serve the thermal energy loads of building 10. The water then returns to subplants 202-212 to receive further heating or cooling.

Although subplants 202-212 are shown and described as heating and cooling water for circulation to a building, it is understood that any other type of working fluid (e.g., glycol, CO2, etc.) can be used in place of or in addition to water to serve the thermal energy loads. In other embodiments, subplants 202-212 can provide heating and/or cooling directly to the building or campus without requiring an intermediate heat transfer fluid. These and other variations to waterside system 120 are within the scope of the present invention.

Each of subplants 202-212 can include a variety of equipment configured to facilitate the functions of the subplant. For example, heater subplant 202 is shown to include a plurality of heating elements 220 (e.g., boilers, electric heaters, etc.) configured to add heat to the hot water in hot water loop 214. Heater subplant 202 is also shown to include several pumps 222 and 224 configured to circulate the hot water in hot water loop 214 and to control the flow rate of the hot water through individual heating elements 220. Chiller subplant 206 is shown to include a plurality of chillers 232 configured to remove heat from the cold water in cold water loop 216. Chiller subplant 206 is also shown to include several pumps 234 and 236 configured to circulate the cold water in cold water loop 216 and to control the flow rate of the cold water through individual chillers 232.

Heat recovery chiller subplant 204 is shown to include a plurality of heat recovery heat exchangers 226 (e.g., refrigeration circuits) configured to transfer heat from cold water loop 216 to hot water loop 214. Heat recovery chiller subplant 204 is also shown to include several pumps 228 and 230 configured to circulate the hot water and/or cold water through heat recovery heat exchangers 226 and to control the flow rate of the water through individual heat recovery heat exchangers 226. Cooling tower subplant 208 is shown to include a plurality of cooling towers 238 configured to remove heat from the condenser water in condenser water loop 218. Cooling tower subplant 208 is also shown to include several pumps 240 configured to circulate the condenser water in condenser water loop 218 and to control the flow rate of the condenser water through individual cooling towers 238.

Hot TES subplant 210 is shown to include a hot TES tank 242 configured to store the hot water for later use. Hot TES subplant 210 can also include one or more pumps or valves configured to control the flow rate of the hot water into or out of hot TES tank 242. Cold TES subplant 212 is shown to include cold TES tanks 244 configured to store the cold water for later use. Cold TES subplant 212 can also include one or more pumps or valves configured to control the flow rate of the cold water into or out of cold TES tanks 244.

In some embodiments, one or more of the pumps in waterside system 120 (e.g., pumps 222, 224, 228, 230, 234, 236, and/or 240) or pipelines in waterside system 120 include an isolation valve associated therewith. Isolation valves can be integrated with the pumps or positioned upstream or downstream of the pumps to control the fluid flows in waterside system 120. In various embodiments, waterside system 120 can include more, fewer, or different types of devices and/or subplants based on the particular configuration of waterside system 120 and the types of loads served by waterside system 120.

Referring now to FIG. 3 , a block diagram of an airside system 130 is shown, according to an exemplary embodiment. Airside system 130 can include a subset of the HVAC devices in HVAC system 100 (e.g., AHU 106, VAV units 116, ducts 112-114, fans, dampers, etc.) and can be located in or around building 10. Airside system 130 can operate to heat or cool an airflow provided to building 10 using a heated or chilled fluid provided by waterside system 120.

In FIG. 3 , airside system 130 is shown to include an economizer-type air handling unit (AHU) 302. Economizer-type AHUs vary the amount of outside air and return air used by the air handling unit for heating or cooling. For example, AHU 302 can receive return air 304 from building zone 306 via return air duct 308 and can deliver supply air 310 to building zone 306 via supply air duct 312. In some embodiments, AHU 302 is a rooftop unit located on the roof of building 10 (e.g., AHU 106 as shown in FIG. 1 ) or otherwise positioned to receive return air 304 and outside air 314. AHU 302 can be configured to operate an exhaust air damper 316, mixing damper 318, and outside air damper 320 to control an amount of outside air 314 and return air 304 that combine to form supply air 310. Any return air 304 that does not pass through mixing damper 318 can be exhausted from AHU 302 through exhaust damper 316 as exhaust air 322.

Each of dampers 316-320 can be operated by an actuator. For example, exhaust air damper 316 can be operated by actuator 324, mixing damper 318 can be operated by actuator 326, and outside air damper 320 can be operated by actuator 328. Actuators 324-328 can communicate with an AHU controller 330 via a communications link 332. Actuators 324-328 can receive control signals from AHU controller 330 and can provide feedback signals to AHU controller 330. Feedback signals can include, for example, an indication of a current actuator or damper position, an amount of torque or force exerted by the actuator, diagnostic information (e.g., results of diagnostic tests performed by actuators 324-328), status information, commissioning information, configuration settings, calibration data, and/or other types of information or data that can be collected, stored, or used by actuators 324-328. AHU controller 330 can be an economizer controller configured to use one or more control algorithms (e.g., state-based algorithms, extremum-seeking control (ESC) algorithms, proportional-integral (PI) control algorithms, proportional-integral-derivative (PID) control algorithms, model predictive control (MPC) algorithms, feedback control algorithms, etc.) to control actuators 324-328.

Still referring to FIG. 3 , AHU 302 is shown to include a cooling coil 334, a heating coil 336, and a fan 338 positioned within supply air duct 312. Fan 338 can be configured to force supply air 310 through cooling coil 334 and/or heating coil 336 and provide supply air 310 to building zone 306. AHU controller 330 can communicate with fan 338 via communications link 340 to control a flow rate of supply air 310. In some embodiments, AHU controller 330 controls an amount of heating or cooling applied to supply air 310 by modulating a speed of fan 338.

Cooling coil 334 can receive a chilled fluid from waterside system 120 (e.g., from cold water loop 216) via piping 342 and can return the chilled fluid to waterside system 120 via piping 344. Valve 346 can be positioned along piping 342 or piping 344 to control a flow rate of the chilled fluid through cooling coil 334. In some embodiments, cooling coil 334 includes multiple stages of cooling coils that can be independently activated and deactivated (e.g., by AHU controller 330, by BMS controller 366, etc.) to modulate an amount of cooling applied to supply air 310.

Heating coil 336 can receive a heated fluid from waterside system 120 (e.g., from hot water loop 214) via piping 348 and can return the heated fluid to waterside system 120 via piping 350. Valve 352 can be positioned along piping 348 or piping 350 to control a flow rate of the heated fluid through heating coil 336. In some embodiments, heating coil 336 includes multiple stages of heating coils that can be independently activated and deactivated (e.g., by AHU controller 330, by BMS controller 366, etc.) to modulate an amount of heating applied to supply air 310.

Each of valves 346 and 352 can be controlled by an actuator. For example, valve 346 can be controlled by actuator 354 and valve 352 can be controlled by actuator 356. Actuators 354-356 can communicate with AHU controller 330 via communications links 358-360. Actuators 354-356 can receive control signals from AHU controller 330 and can provide feedback signals to controller 330. In some embodiments, AHU controller 330 receives a measurement of the supply air temperature from a temperature sensor 362 positioned in supply air duct 312 (e.g., downstream of cooling coil 334 and/or heating coil 336). AHU controller 330 can also receive a measurement of the temperature of building zone 306 from a temperature sensor 364 located in building zone 306.

In some embodiments, AHU controller 330 operates valves 346 and 352 via actuators 354-356 to modulate an amount of heating or cooling provided to supply air 310 (e.g., to achieve a set-point temperature for supply air 310 or to maintain the temperature of supply air 310 within a set-point temperature range). The positions of valves 346 and 352 affect the amount of heating or cooling provided to supply air 310 by cooling coil 334 or heating coil 336 and may correlate with the amount of energy consumed to achieve a desired supply air temperature. AHU controller 330 can control the temperature of supply air 310 and/or building zone 306 by activating or deactivating coils 334-336, adjusting a speed of fan 338, or a combination thereof.

Still referring to FIG. 3 , airside system 130 is shown to include a BMS controller 366 and a client device 368. BMS controller 366 can include one or more computer systems (e.g., servers, supervisory controllers, subsystem controllers, etc.) that serve as system level controllers, application or data servers, head nodes, or master controllers for airside system 130, waterside system 120, HVAC system 100, and/or other controllable systems that serve building 10. BMS controller 366 can communicate with multiple downstream building systems or subsystems (e.g., HVAC system 100, a security system, a lighting system, waterside system 120, etc.) via a communications link 370 according to like or disparate protocols (e.g., LON, BACnet, etc.). In various embodiments, AHU controller 330 and BMS controller 366 can be separate (as shown in FIG. 3 ) or integrated. In an integrated implementation, AHU controller 330 can be a software module configured for execution by a processor of BMS controller 366.

In some embodiments, AHU controller 330 receives information from BMS controller 366 (e.g., commands, setpoints, operating boundaries, etc.) and provides information to BMS controller 366 (e.g., temperature measurements, valve or actuator positions, operating statuses, diagnostics, etc.). For example, AHU controller 330 can provide BMS controller 366 with temperature measurements from temperature sensors 362-364, equipment on/off states, equipment operating capacities, and/or any other information that can be used by BMS controller 366 to monitor or control a variable state or condition within building zone 306.

Client device 368 can include one or more human-machine interfaces or client interfaces (e.g., graphical operator interfaces, reporting interfaces, text-based computer interfaces, client-facing web services, web servers that provide pages to web clients, etc.) for controlling, viewing, or otherwise interacting with HVAC system 100, its subsystems, and/or devices. Client device 368 can be a computer workstation, a client terminal, a remote or local interface, or any other type of operator interface device. Client device 368 can be a stationary terminal or a mobile device. For example, client device 368 can be a desktop computer, a computer server with an operator interface, a laptop computer, a tablet, a smartphone, a PDA, or any other type of mobile or non-mobile device. Client device 368 can communicate with BMS controller 366 and/or AHU.

Referring now to FIGS. 4A-4B, system 400 is shown, according to some embodiments. System 400 includes conditioned space 402, according to some embodiments. Conditioned space 402 may be a room, an area, a floor of a building, etc., or any other space to which heating ventilating and/or cooling and other control is provided and monitored. System 400 includes HVAC equipment 404 configured to provide heating, ventilation, or cooling to conditioned space 402, according to some embodiments. HVAC equipment 404 may be configured to provide heating, ventilation, and/or cooling to conditioned space 402 via one or more ducts, vents, fans, etc. Conditioned space 402 may have a temperature distribution throughout various areas of conditioned space 402. For example, conditioned space 402 may have a temperature T₁ near HVAC equipment 404, and a temperature T₂ near a window or door 409. If HVAC equipment 404 is in an operating state to provide cooling to conditioned space 402, T₂ may be greater than T₁. Likewise, if HVAC equipment 404 is in an operating state to provide heating to conditioned space 402, T₂ may be less than T₁. Conditioned space 402 may have an average temperature (e.g., an average with respect to area of conditioned space 402) T_(avg).

As shown in FIG. 4A, system 400 includes a building control device (e.g., building controller, control device, etc.), shown as thermostat 406, according to some embodiments. Thermostat 406 is configured to adjust an operation of HVAC equipment 404 by providing HVAC equipment 404 with manipulated variable u, according to some embodiments. In some embodiments, manipulated variable u is a command to transition HVAC equipment 404 between an on state and an off state. In some embodiments, manipulated variable u is a command to transition HVAC equipment 404 between a cooling state, a heating state, and an off state. For example, if HVAC equipment 404 includes equipment configured to provide heating to conditioned space 402, thermostat 406 may provide the heating equipment of HVAC equipment 404 configured to provide heating to conditioned space 402 with manipulated variable u_(H) which indicates a command to transition the heating equipment of HVAC equipment 404 between an on state (i.e., a state which causes the heating equipment to operate to provide heating to conditioned space 402) and an off state (i.e., a state which causes the heating equipment to be in-operational or to not provide heating to conditioned space 402). Likewise, if HVAC equipment 404 includes cooling equipment configured to provide cooling to conditioned space 402, thermostat 406 may be configured to provide the cooling equipment with a manipulated variable u_(C) to transition the cooling equipment between an on state (i.e., a state which causes the cooling equipment to operate to provide cooling to conditioned space 402) and an off state (i.e., an in-operational state of the cooling equipment). In some embodiments, manipulated variable u represents either u_(H) or u_(C).

In some embodiments, thermostat 406 includes sensor 410 and controller 408. In some embodiments, sensor 410 is configured to measure a performance variable y of conditioned space 402. For example, sensor 410 may be a temperature sensor (e.g., a negative temperature coefficient thermistor, a resistance temperature detector, a thermocouple, a semi-conductor based temperature sensor, etc.) configured to measure a temperature of conditioned space 402. In some embodiments, sensor 410 is configured to measure a temperature of conditioned space 402 near thermostat 406. In some embodiments, sensor 410 is configured to measure the average temperature T_(avg) of conditioned space 402. In some embodiments, multiple sensors 410 are disposed about conditioned space 402 and are configured to measure the temperature or other ambient condition of conditioned space 402 in multiple locations. In some embodiments, the temperature measured by sensor 410 is the performance variable y. In some embodiments, sensor 410 is configured to measure an indoor air quality (e.g., concentration of airborne particulate in ppm), a humidity sensors configured to measure humidity of conditioned space 402, etc., or any other sensor configured to measure one or more conditions of conditioned space 402. In some embodiments, sensor 410 represents a plurality of the same type of sensors, or a plurality of various types of sensors.

Controller 408 of thermostat 406 is configured to determine values of the manipulated variable u to transition HVAC equipment 404 between various states (e.g., an on state and an off state, a cooling state and a heating state, etc.) based on the performance variable y measured by sensor 410, according to some embodiments. In some embodiments, controller 408 is configured to determine the manipulated variable u based on the performance variable y and a setpoint r. The setpoint r may indicate a desired temperature or a desired value of the performance variable y of conditioned space 402. In some embodiments, setpoint r is received via user interface 412 of thermostat 406. For example, a user may input a desired temperature of conditioned space 402 (e.g., 70 degrees Fahrenheit), and controller 408 may use the setpoint r, one or more values of the performance variable y, and a control algorithm to determine u to achieve the setpoint r for conditioned space 402.

In some embodiments, controller 408 receives the setpoint r from user interface 412. In some embodiments, controller 408 displays the performance variable y at user interface 412. In some embodiments, controller 408 is configured to determine a filtered, smoothed, or adjusted value z of performance variable y and provide value z at user interface 412. The filtered, smoothed, or adjusted value z of performance variable y may represent a time averaged value of performance variable y which may advantageously reduce minor fluctuations of performance variable y from displaying on the user interface 412, according to some embodiments. In some embodiments, the reduced number of fluctuations of value z may reduce the required refresh rate of a display in the user interface 412.

Referring now to FIG. 4B, system 400 is shown, according to some embodiments. System 400 as shown in FIG. 4B operates similarly to or the same as system 400 of FIG. 4A, however, controller 408 is positioned remotely from conditioned space 402. For example, controller 408 may be positioned at HVAC equipment 404, at a remote server, in a back room, in a hallway, etc. In some embodiments, controller 408 receives the performance variable y from sensor 410, the setpoint r, from user interface 412. In some embodiments, controller 408 is configured to operate similarly as described above in greater detail with reference to FIG. 4A. In some embodiments, controller 408 is configured to provide the filtered value z of the performance variable y to user interface 412 for display. In some embodiments, the controller 408 is configured to receive inputs from the user interface 412 and to supply commands to building device 411 (e.g., IoT device, smart device, smart hub, etc.) to control a characteristic of the conditioned space 402 (e.g., light intensity, sound intensity, etc.).

In some embodiments, the display may use a variety of display technologies such as light emitting diode (LED), organic light emitting diode (OLED), liquid crystal display (LCD), organic light-emitting transistor (OLET), surface-conduction electron-transmitter display (SED), field emission display (FED), digital light processing (DLP), liquid crystal on silicon (LCoC), or any other display technologies known in the art. In some embodiments, display 505 includes a touch sensitive surface configured to receive an input from a user to allow the user to interact with the touchless building control device 500 and provide a user input to the touchless building control device 500. In some embodiments, display 505 is configured to present visual media without requiring a backlight. As shown, display 505 is an electrophoretic display which uses energy only when changing state (e.g., when changing the visual media on display 505), and thereby uses significantly less energy than a backlit display. In some embodiments, display 505 is an electrophoretic display which significantly reduces the power requirements of the touchless building control device 500 when compared to other display technologies used in the art.

In some embodiments, display face 507 is angularly offset from the mounting surface 502 and mounting face 504 by an angle, shown as display angle 509, according to some embodiments. In some embodiments, the display angle 509 is selected based on the dimensions of the display 505, Americans with Disabilities Act (ADA) standards, and other codes or regulatory standards. For example, in some embodiments, the distal end 511 of display face 507 should not exceed 4 inches from the mounting surface 502 to comply with an ADA standard. In some embodiments, the display angle 509 is between 5 degrees and 90 degrees. In some embodiments, the display angle 509 is between 20 degrees and 35 degrees. In some embodiments, the display angle 509 is 33 degrees. In some embodiments, the protrusion distance 512 is defined between the mounting surface 502 to the furthest portion of touchless building control device 500 from mounting surface 502.

Referring now to FIG. 9 , a pair of touchless building control devices 500 are mounted to a mounting surface 502, according to some embodiments. As shown, a first person, shown as tall user 902, a second person, shown as short user 904, and a seated person, shown as seated user 906 are all positioned on a horizontal surface, shown as floor 910. As shown, seated user 906 is seated in a chair, shown as wheelchair 908. In some embodiments, each user has a first facial plane, shown as eye level plane 901, a second facial plane, shown as head center plane 903. In some embodiments, eye level plane 901 is defined as a plane though a user's eyes extending from the front of the user's eyes to the back of the user's eyes. In some embodiments, head center plane 903 is defined as a plane through the center of the user's head and perpendicular to eye level plane 901. In some embodiments, a line of sight 905 (e.g., an effective line of sight, etc.) extends from an intersection between head center plane 903 and eye level plane 901 towards the display 505 of the touchless building control device 500. In some embodiments, display angle 509 is selected to position display axis 508 in a parallel direction to line of sight 905 for a wide range of users within a user access distance 907. In some embodiments, user access distance 907 is defined as a horizontal distance between head center plane 903 and the mounting surface 502. In some embodiments, user access distance 907 is defined as a distance wherein the touchless building control device is within an arm's reach (e.g., 1 feet, 2 feet, 3 feet, 4 feet, etc.) of the user. In some embodiments, user access distance 907 is not within an arm's reach of the BCD and may be determined based on the gesture detectable range 1104. For example, if gesture sensors 544 are cameras capable of detecting user motions at a distance of up to 10 feet away from the cameras, the user access distance 907 may be up to 10 feet. As shown in FIG. 9 , a user eye height 909 is defined between the eye level plane 901 and a plane containing outer radius 520 parallel to the floor 910. In some embodiments, tall user 902 is the height of a 95^(th) percentile male (e.g., approximately 74 inches tall). In some embodiments, short user 904 is the height of a 5^(th) percentile female (e.g., approximately 59 inches tall). In some embodiments, mounting height is defined as a distance between outer radius 520 and floor 910. In some embodiments, touchless building control device 500 is mounted at a first mounting height, shown as upper height 912. Upper height 912 may be approximately 60 inches, according to some embodiments. Upper height 912 may be suitable for tall user 902 and short user 904, but not for seated user 906, according to some embodiments. In some embodiments, a version of touchless building control device 500 may be configured to have a small (e.g., 1 degree, 5 degree, 10 degree, 13 degree, etc.) display angle 509 for mounting at upper height 912.

In some embodiments, touchless building control device 500 is mounted at a second mounting height, shown as accessible height 914. Accessible height 914 may be between 15 inches and 48 inches, according to some embodiments. In some embodiments, accessible height 914 is 36 inches. Accessible height 914 may be suitable for tall user 902, short user 904 and seated user 906. In some embodiments, accessible height 914 allows tall user 902, short user 904 and seated user 906 to view the display 505, and provide motion inputs (e.g., gesture inputs, gesture control, etc.) using a distal end 920 of a user's upper appendage 922. In some embodiments, display angle 509 is approximately 33 degrees when mounted at accessible height 914. In some embodiments, display angle 509 is equal to or greater than 15 degrees and less than or equal to 45 degrees. In some embodiments, display angle 509 is selected to allow a plane containing display 505 (e.g., display face 507) to be easily viewable by a variety of users (e.g., users 902, 904, 906, etc.). For example, in some embodiments, a display angle of approximately 33 degrees at an accessible height 914 of 36 inches may cause the display 505 to be substantially perpendicular when viewed by a variety of users (e.g., users 902, 904, 906) at a common distance (e.g., within an arm's reach, 3 feet, 2 feet, 4 feet, etc.) from the touchless building control device 500.

In some embodiments, touchless building control device 500 is mounted at a third mounting height, shown as lower height 916. Lower height 916 may be 15 inches, according to some embodiments. Lower height 916 may be suitable for seated user 906 and less suitable for tall user 902 and short user 904. In some embodiments, lower height 916 allows tall user 902, short user 904, and seated user 906 to view the display 505, and provide motion inputs (e.g., gesture inputs, gesture control, etc.) using a distal end 920 of a user's upper appendage 922 or a distal end 924 of a user's lower appendage 926 (e.g., a foot on a leg, etc.). As shown, touchless building control device 500 may be configured to have a large display angle 509 (e.g., 90 degree, 80 degree, 75 degree, etc.) to facilitate a user 902, 904, 906 viewing display 505 while the user 902, 904, 906 is in a standing or seated position near touchless building control device 500.

A person having ordinary skill in the art will appreciate that display angle 509 and display axis 508 are related, according to some embodiments. For example, modifying display angle 509 will change the direction of display axis 508 relative to mounting surface 502. In some embodiments, display angle 509 is selected for an average user at a user access distance 907 where the user does not need to strain (e.g., tilt their head, bend down, crouch, etc.) to view display 505. In some embodiments, an optimal display angle 509 can be determined based on an equation including variables representing user access distance 907, user eye height 909, and characteristics of line of sight 905 (e.g., a desirable angular offset amount of line of sight 905 from floor 910). In some embodiments, an optimal display angle 509 is selected for a representative average user (e.g., a user having an average height, arm length, etc.). In some embodiments, display angle 509 is selected so that line of sight 905 is substantially parallel to display axis 508 (e.g., within ±5 degrees, etc.). In some embodiments, display angle 509 is selected so that line of sight 905 is substantially parallel to display axis 508 when a user is at a user access distance 907 and has a comfortable head position. In some embodiments, a comfortable head position is defined as a position when eye level plane 901 is approximately parallel to the floor 910 (e.g., ±15 degrees, etc.).

Referring now to FIG. 10 , a touchless building control device 500 is mounted to a mounting surface 502. As shown, a user 1002 is within an occupancy detectable range 1004 of occupancy sensor 530. In some embodiments, the touchless building control device 500 is configured to activate (e.g., enable) identification sensor 532 upon the occupancy sensor 530 detecting an object (e.g., a user, animal, etc.) within occupancy detectable range 1004. As shown, user 1002 has a first identifiable object, shown as first transponder 1006 attached to a lanyard, a second identifiable object, shown as second transponder 1008 attached to a belt clip or in a front pocket, and a third identifiable object, shown as third transponder 1010 in a back pocket, wallet or bag. As shown in FIG. 10 , user 1002 is within identification detectable range 1012 of identification sensor 532. As shown, identification detectable range 1012 extends equally in all directions from touchless building control device 500. In some embodiments, identification detectable range 1012 does not extend equally in all directions from touchless building control device 500. In some embodiments, touchless building control device 500 is mounted to mounting surface 502 at accessible height 914 to position identification sensor 532 near the positions of transponders 1006, 1008, and 1010 (i.e. common locations of transponders on a user 1002), in addition to the various user accessibility conditions discussed herein.

Referring now to FIGS. 11 and 12 , a touchless building control device 500 is shown with a distal end of a user's appendage, shown as hand 1102, providing an input to the touchless building control device 500, according to some embodiments. In some embodiments, a user provides an input to the touchless building control device 500 by one or more detectable motions (e.g., gestures, movements, body positons, body orientations, etc.), shown as user motion 1204, within gesture detectable range 1104. As shown in FIG. 11 , hand 1102 is moved in a gesture detectable range 1104 of gesture sensors 544 in direction 1106. The gesture detectable range 1104 is a cumulative detection range including the detection range of each gesture sensor 544 disposed in ring 540, according to some embodiments. As shown, the gesture detectable range 1104 extends above, below, on top of, and to the sides of touchless building control device 500. Gesture detectable range 1104 is shown to have a left side 1108, a right side 1110, a top side 1112, a bottom side 1114, according to some embodiments. As shown, gesture detectable range 1104 extends into three dimensional space. Gesture detectable range 1104 may have one or more sides relating to a depth of the gesture detectable range (e.g., a side offset from the plane containing the display 505, etc.). In some embodiments, hand 1102 moves between left side 1108, right side 1110, top side 1112, and bottom side 1114 to interact with the touchless building control device 500. For example, as shown in FIG. 11 , hand 1102 may move horizontally in direction 1106 between left side 1108 and right side 1110 within gesture detectable range 1104 to supply an input to the touchless building control device 500.

In some embodiments, the touchless building control device 500 is configured to scroll between selectable options 1120 on graphical user interface 1124 displayed on display 505 when hand 1102 is moved between the right side 1110 and the left side 1108. For example, when hand 1102 is moved from left side 1108 to right side 1110 the graphical user interface 1124 may scroll the selectable options 1120 to the right (e.g., direction 1106). In some embodiments, the graphical user interface 1124 may display a cursor and a user may be able to manipulate the cursor position on graphical user interface 1124 using motion control (e.g., by moving hand 1102 within gesture detectable range 1104). As shown in FIG. 11 , graphical user interface 1124 includes motion suggestions, shown as gesture suggestions 1121. Gesture suggestions 1121 may be located on graphical user interface 1124 to instruct a user on how to interact with the gesture sensors 544. In some embodiments, touchless building control device 500 is configured to select a selectable option 1120 when hand 1102 moves from the bottom side 1114 to top side 1112 near the middle of the gesture detectable range 1104 (e.g., centered between left side 1108 and right side 1110). In some embodiments, touchless building control device 500 is configured to exit a selectable option 1120 or return to a menu display when hand 1102 is moved from top side 1112 to bottom side 1114 near the middle of the gesture detectable range 1104. In some embodiments, touchless building control device 500 is configured to adjust a temperature setting (e.g., setpoint r of FIG. 4A and FIG. 4B), when hand 1102 moves between top side 1112 and bottom side 1114 near left side 1108 or right side 1110. For example, touchless building control device 500 may be configured to lower a selectable value (e.g., temperature setting, humidity setting, light setting, etc.) when hand 1102 moves from top side 1112 to bottom side 1114 in the direction 1202 near left side 1108. In some embodiments, touchless building control device 500 is configured to raise a selectable value (e.g., temperature setting, humidity setting, light setting, etc.) when hand 1102 moves from bottom side 1114 to top side 1112 near the left side 1108 and/or right side 1110. A person having ordinary skill in the art will appreciate that a large number of gestures (e.g., motions of hand 1102) may be identifiable within gesture detectable range 1104, each of which configured to supply a desired input to touchless building control device 500. In some embodiments, gesture sensors 544 may comprise one or more camera (e.g., depth aware camera, time-of-flight camera, etc.), and gesture detectable range 1104 may be shaped differently than shown in FIG. 12 . In some embodiments, gesture sensors 544 may be a pair of stereo cameras which may detect light (e.g., visible light, invisible light) reflected off a portion of a user (e.g., user's skin, user's osseous matter, etc.) to detect one or more motions, positions, and or orientations of a user (e.g., a hand 1102 in a pointing or first position, an distal end 920 raised or pointed near touchless building control device 500, etc.).

In some embodiments, light emitting device 534 and/or light emitting portion 550 may emit light of varying intensity and color near hand 1102. For example, as shown in FIG. 11 , light emitting portion 550 is emitting a scrolling light 1130. In some embodiments, scrolling light 1130 may be a green colored light that is emitted along a top surface of the touchless building control device 500 by one or more light emitting portion 550. In some embodiments, the scrolling light 1130 may include a portion of high intensity which moves along the top surface of the touchless building control device 500 as hand 1102 moves across gesture detectable range 1104. For example, as shown in FIG. 11 , scrolling light 1130 has a high intensity portion 1132 and a standard intensity portion 1134. In such example, high intensity portion 1132 follows hand 1102 in the direction 1106. In some embodiments, touchless building control device 500 may be configured to cause light emitting portion 550 to flash or display colors to indicate a selection of a selectable option 1120. In some embodiments, touchless building control device 500 may be configured to display a blue colored light when a selectable value (e.g., temperature setting, humidity setting, light setting, etc.) is lowered. For example, touchless building control device 500 may be configured to display blue light of varying intensity along a left side of touchless building control device 500 with functionality similar to scrolling light 1130. In some embodiments, touchless building control device 500 may be configured to display light of one or more color on one or more sides of the touchless building control device 500 to provide feedback to the user of recognition of a gesture (e.g., motion of hand 1102) received by touchless building control device 500.

In some embodiments, access to touchless building control device 500 is granted to users though a tiered system, with each tier having access to a different set of building controls (e.g., building-level controls 1412, zone-level controls 1414, and condition-level controls 1416. For example, user having a highest level of access (e.g., tier 1 access) is able to access all of the building-level controls 1412, zone-level controls 1414, condition-level controls 1416, and administrative settings (e.g., settings for modifying a list of authorized users, settings for locking a touchless building control device 500, settings for manipulating touchless building control device 500 software such as updates, etc.), according to some embodiments. In some embodiments, a user having a second highest level of access (e.g., tier 2 access) is able to access building-level controls 1412, zone-level controls 1414, condition-level controls 1416, but not administrative controls. In some embodiments, a user having a third highest level of access (e.g., tier 3 access) may be able to access zone-level controls 1414 and condition-level controls 1416. In some embodiments, a user having a fourth highest level of access (e.g., tier 4 access) may be able to access only specific zone level controls such as lights 1426 and shades 1428. In some embodiments, a user having a lowest level of access (e.g., tier 5 access), may not be able to access building-level controls 1412, zone-level controls 1414, or condition-level controls 1416, but is able to view the current status, state, and criteria of the conditioned area and can submit requests to a user having higher level access (e.g., tier 1 access) to have touchless building control device 500 settings changed (e.g., temperature 1432).

In some embodiments, a user is not associated with a touchless building control device 500 system. In some embodiments, a non-associated user (e.g., a user is identified but no user profile exists within the touchless building control device system) is denied access to touchless building control device 500. For example, a building visitor, an intruder, or an unauthorized user may attempt to interact with touchless building control device 500. In such example, identification sensor 532 gathers an identifiable characteristic (e.g., RFID badge, Bluetooth beacon information, short range wireless beacon information, etc.) from the user and the touchless building control device 500 system determines that the user is unauthorized, and may refuse to unlock the touchless building control device 500. In some embodiments, the touchless building control device 500 compares the identifiable characteristic to a database of user information and associated identifiers.

In some embodiments, touchless building control device 500 is configured to receive an input from all users without identifying the user. In some embodiments, the touchless building control device 500 is configured to receive an input from all users and determines and stores an identifiable characteristic (e.g., an image of the user's face, a Bluetooth beacon, a RFID transponder, etc.) for each user that interacts with the touchless building control device 500.
